TAPTITE 2000® SP fasteners have a shorter point than standard TAPTITE 2000® fasteners to maximize full thread engagement in blind holes, particularly in non-ferrous materials.

Taptite 2000 spTAPTITE 2000® SP fasteners are primarily used in aluminum and therefore are supplied with CORFLEX®-N heat treatment to minimize the potential of stress corrosion. When used in steel material, TAPTITE 2000® SP fasteners can be ordered with the case hardened or CORFLEX®-I heat treatment.

The short point of the TAPTITE 2000® SP fastener maximizes the amount of full thread engagement in blind holes. Increasing the full thread engagement is often critical in shallow depth holes. In many cases the failure mode can be shifted from internal thread stripping to fastener fracture, which is typically desired in castings. In deeper holes, the shorter ”SP” point may allow a shorter fastener, saving weight and cost.
